Definitions

  • melt passage branches in the nozzle manifold with each branch leading to a melt bore through one of the nozzles.
  • the nozzles are fixed in place in the cooled mold and thermal expansion and contraction of the heated nozzle manifold causes the nozzle manifold to slide across the rear ends of the nozzles. It is very important that each branch of the melt passage be aligned exactly with the melt bore through the nozzle, particularly in view of the high temperature and pressure conditions of an injection molding system.
  • holes 100 are made enough larger than the screws 94 extending through them to allow each nozzle manifold 10 to slide across the rear ends 92 of the nozzles 78 which are fixed in place.
  • the amount of movement at each nozzle 78 is precalculated and the nozzle manifolds 10 made with each branch of the melt passage 72 dimensioned to slide into exact alignment with the melt bore 80 of one of the nozzles 78 as the operating temperature is reached.
  • the locating pin 108 allows each nozzle manifold 10 to move in the first direction parallel to the central axis 32, but prevents it moving in the second direction perpendicular to the first direction.
  • the combination of the connector bushing 50 and the locating pin 108 allow sufficient movement of each nozzle manifold 10 in both the first and second directions to provide for thermal expansion of the heated manifolds 12, 14 relative to the cooled mold 16.
  • this movement is reversed if the heating elements 60, 61, 76 are turned off and the manifolds 10, 12, 14 cool off for disassembly or repair.
  • locating pins 108 and cams 114 are shown, in other embodiments other locating means can be used which locate the nozzle manifolds 10 in the second direction, but allow them to slide freely in the first direction.
